I need to watch this whole series, I have two of these L models, they had been running before I bought them. I've got two more modern 5000 series Walk behinds; one I fixed up and it works great, the other needs a governor adjustment as it runs flat out. My general sense is the L's are heavier duty than later ones, plus they have oil filters and sediment bowls.
I have my battery tray and hood and other stuff for the L8 but I want to mount the breather down like you have here,is that mounted on the top center trans to engine bolt?
